Diesel Powered Equipment Applications

Horizontal Grinder | Rock Crusher | Tub Grinder

Situation
A horizontal grinder‘s engine drives a hammermill through a set of belts. This harsh application applies a large load to the clutch output shaft while it reduces the size of waste materials.

Problem
Large overhung loads and shockloads can damage clutches, belts and even engines.

HPTO15

• Models rated up to 1600 HP
• High belt-load capacity
• Auxiliary pump drives

Solution
An HPTO, a Hydraulic Power Take-Off, provides a reliable solution to all the concerns. This microprocessor controlled, hydraulically applied wet clutch isolates these damaging loads from harming the engine and machine.

...is a rugged computer control for the clutch operation. This interface quickly tells the operator what is going on in the clutch and allows for quick troubleshooting. The built-in safety features can prevent unsafe operations.

• SAE J1939 CAN Compatible
• Self Diagnostic
• Prevents operator abuse of Machine and Clutch
• Robust design for Off-Highway Applications

Advanced 3
– Wet Clutch Controller

Basic 2
— Dry Clutch Controller

Situation
Rock crushers use a high inertia impactor, cone or jaw crusher to crush rock. Getting these crushers engaged to the engine requires skilled operators.

Problem
Inexperienced operators can damage manual clutches while starting machine. The small pilot bearings have a short service life and transfer belt-load into the engine crankshaft.

HPTO12

• Up to 460 HP Rating
• Self-adjusting
• Oil-lubricated

Solution
The microprocessor controller monitors the engine during engagement to properly synchronize the engine and crusher thus automating the process. The design of the HPTO12 eliminates the problem pilot bearing and replaces it with a self-supported, oil lubricated bearing. The combination provides an unparalleled solution for this punishing application.

Situation
A tub grinder’s diesel engine turns a hammermill at engine speed to pulverize material. Designed to reduce wood, yard, and demolition waste, the equipment is subject to significant shockloads when foreign material is dropped into the tub.

Problem
The shockload can break universal joint causing it to fail. This can potentially cause costly damage to the equipment.

UJT

• Single, double and triple discs with torque to 9,066 lb-ft.
• Machined to accept SAE flanged driveshafts. Wing bearing connections are also available.

Solution
A UJT Series Torque Limiter is mounted between the universal joint and the hammermill. The torque setting is placed at 200% of the engine’s peak torque. This setting is below the mechanical clutch’s torque setting and well below the universal joint's ultimate strength thus protecting both from the shockload.
